All in the same time, I mean in the same plate? I guess you don’t have aligned the bed or you have damaged some parts of the fep, check where was each part on the bed. The horns look fine but the others parts no.
Yes everything was on the same plate. I’ve done releveling few times and still i have the same problem. May it be that fep is in bad condition. Horns were much smaller(less height in z axis). I had the same problem with previous project. Also i think that my exposure is bit to low and there is weak adhesion between layers and during peeling from fep it may shift or strech a bit
Nice resin prints. 
Check if the same height of horns on the others parts are smoothed or not, maybe you need grease the up/down screw
Z axis is working fine. That was exposure issue. Resin wasn’t cured enough
Download a test and print at differents times to check what is the best then.
Im using uv tools to do multiple exposure time test at once. Ill print these tests today(finally have time for that)

A few hours? 
Did you start with a base mesh? That’s a pretty well developed sculpt for just a few hours. Nice work!
Few is more like an 8h in this case :p. Yes every time i start from scratch ( i have to learn how to re-use my stuff. Thanks
